Data synchronous transmission method based on sqlite

Abstract

The invention relates to a data synchronous transmission method based on the sqlite. Compared with the prior art, the data synchronous transmission method overcomes the defect that a reliable and quick data transmission method does not exist. The method includes the following steps that a local database is initialized; local data are stored and updated; a network is monitored through a data synchronizing module; data are received through a server; the data are fed back through the server; versions are compared. According to the data synchronous transmission method based on the sqlite, data transmission in a network disconnection environment and a networking environment is achieved, and the data cannot conflict with one another.

Description

[0001] technical field [0002] The invention relates to the technical field of data transmission, in particular to a method for synchronous data transmission based on sqlite. [0003] Background technique [0004] The rapid development of the mobile Internet, the improvement of network transmission technology and the popularization of smart terminals have led to the emergence of various smart terminal application products, bringing great convenience to people's daily life and office work. These products often need to interact with the server-side program in the process of using the network to achieve the purpose of uploading, obtaining and synchronizing data. There are generally two types of traditional interaction methods: [0005] 1. Online C / S communication method, which provides instant communication between the client and the server through the network. The advantage of this method is that the data is synchronized in real time, and there is no problem of synchronous ...

Problems solved by technology

[0005] 1. Online C / S communication method, which provides instant communication between the client and the server through the network. The advantage of this method is that the data is synchronized in real time, and there is no problem of synchronous data conflicts. The disadvantage is that it requires network stability. Higher, a network failure during the communication process will cause data communication failure, users cannot continue to use or even data loss;

[0006] 2. The traditional offline synchronization method. The basic principle of this method is that the data processed by the user on the terminal first exists locally. When there is a network, the user manually selects the synchronization data to the server. The degree of dependence on the network also reduces the real-time performance of data synchronization between the client and the server, and this type of synchronization method generally works better when used on a single terminal. Once multiple terminals are used under the same account at the same time, it is easy to cause data conflict

[0007] However, if the above two methods are combined, the problem of data conflict will arise again, and the current data synchronization method will also cause its response speed to become slower and slower as the amount of data transmission increases.
